As shown in FIG. 5, in the first embodiment, the mounting surface 91 of the wiring member 13 has a sensor fixing portion 56 to which the magnetic detection sensor 81c is fixed, a center 81c of the magnetic detection sensor 81, and a magnetic member. It has positioning holes 57 and 58 for aligning the center 11c of 11 and the center 31c of the coil 31 on the coaxial Lc.
Next, an example of how to fix the magnetic detection sensor 81, the magnetic member 11, and the coil 31 to the mounting surface 91 will be described.

(1) First, the position of the center 81c of the magnetic detection sensor 81 is determined by aligning and fixing the magnetic detection sensor 81c to the sensor fixing portion 56 of the wiring member 13 by using an alignment jig or the like. In FIG. 5, reference numerals 59 are lands provided on the wiring member 13 for establishing an electrical connection, and are provided at four locations.
As shown in FIG. 6, by aligning the four terminals 69 of the magnetic detection sensor 81 with the land 59 and soldering them, the magnetic detection sensor 81 is fixed in a state of being positioned on the mounting surface 91.
The mounting surface 92 is also provided with the same sensor fixing portion and positioning hole, but since the structure is the same as that of the mounting surface 91, the description thereof will be omitted.

(2) Next, the magnetic member 11 is positioned on the mounting surface 91 by aligning and fixing the magnetic member 11 with reference to the center 81c of the magnetic detection sensor 81 using an alignment jig or the like. It is fixed in the fixed state. The magnetic member 11 is fixed to the mounting surface 91 by plating and soldering. Of course, it may be fixed with an adhesive.

(3) The positioning pins 75 and 77 of the alignment jig are inserted into the positioning holes 57 and 58 of the mounting surface 91 in the state shown in FIG. Here, the positioning hole 57 is a reference hole having a shape consistent with the positioning pin 75, but the positioning hole 58 has an elongated hole shape long in the X direction. This elongated hole shape facilitates the insertion of two positioning pins into the two positioning holes.
Subsequently, with the positioning pins 75 and 77 inserted into the positioning holes 57 and 58, the coil 31 is inserted into the positioning pins 75 and 77. As a result, the state shown in FIG. 5 is obtained. Since the positioning holes 57 and 58 are provided to align the center 81c of the magnetic detection sensor 81, the center 11c of the magnetic member 11, and the center 31c of the coil 31 on the coaxial Lc, the coil 31 is also provided. Fix it in the positioned state. The coil 31 is fixed to the magnetic member 11 on the mounting surface 91 with an adhesive.

Further, as shown in FIGS. 4 and 5, in the first embodiment, both ends in the Z direction, which are a part of the magnetic member 11, are fixed to the effective sides 85 and 86 of the coil 31 with respect to the magnet 33. Here, the "effective side" is a side required to act between the magnet 33 and the coil 31 to generate an electromagnetic force.
As a result, the magnetic member 11 has a role of generating a magnetic force between the magnet 33 and the magnet 33 when the coil 31 is not energized, and when the coil 31 is energized, the magnet 33 and the coil 31 It can play a role as a back yoke that enhances the magnetic force between the two.

Further, as shown in FIGS. 1 and 2, in the first embodiment, the wiring member 13 has an extending portion 95 extending from the mounting surface 91 in the direction along the surface of the mounting surface 91. A cutout portion 97 is formed at a portion connected to the extending portion 95.

Further, as shown in FIGS. 4 and 5, in the first embodiment, the wiring member 13 includes lands 201 and 202 for electrically connecting one end 101 and the other end 102 of the coil 31, respectively, and the coil. The winding start position 105 and the winding end position 106 of 31 are formed so as to correspond to the respective lands 201 and 202, respectively.
Here, the "corresponding position" does not require that the winding start position 105 and the winding end position 106 of the coil 31 exactly coincide with the respective positions of the lands 201 and 202 in the Z direction in this specification. .. It is used in the sense that the winding start position 105 and the winding end position 106 of the coil 31 may be arranged relative to each other with respect to the respective positions of the lands 201 and 202. In other words, the winding start position 105 and the winding end position 106 of the coil 31 are used in a relative arrangement as long as they overlap each other of the existing regions of the lands 201 and 202 in the X direction. This "overlapping" does not require strict overlap, and also includes relative arrangements that do not overlap due to slight deviation. For example, the winding start position 105 of the coil 31 is a position on the inner circumference of the coil 31 (positioning hole 57), instead of lowering one end 101 of the coil to a substantially central position in the width direction of the land 201 by the routing method as shown in FIG. It may be directly lowered so that the distance from the land 201 to the existing area) is shortened.
As a result, one end 101 and the other end 102 of the lead wire at the winding start position 105 and the winding end position 106 of the coil 31 can be directly connected to the lands 201 and 202, and the connection by solder or the like is easy.

Further, in the first embodiment, since the wiring member 13 includes a plurality of mounting surfaces 91 and 92, it is possible to easily correspond to a runout correction structure having two or more axes.
Further, since the line width of the portion 14 connecting the mounting surfaces 91 and 92 is narrower than the width of the mounting surfaces 91 and 92 in the same direction, the wiring member 13 can be easily routed by bending and adjacent to each other. Fine adjustment of the positions of the mounting surfaces 91 and 92 can be easily performed. In addition, the stress generated in the wiring member 13 when bent can be reduced.
